The Claim

Consuming extra virgin olive oil rich in polyphenols for 4 weeks significantly increases urinary hydroxytyrosol-glucuronide (HT-glucuronide) excretion in healthy young adults compared with regular olive oil, as indicated by a statistically significant beta coefficient (β = 1.24, 95% CI: 0.13–2.35, p = 0.028), thereby confirming the absorption and metabolism of olive oil phenolic compounds.

Cause and effect
1 study reviewed
In plain English

Eating extra virgin olive oil that is high in polyphenols (natural antioxidants) for four weeks increases the amount of a breakdown product in urine compared to regular olive oil. This shows the body absorbs and processes the antioxidants from the oil.

See the scientific wording

Consuming extra virgin olive oil rich in polyphenols for 4 weeks significantly increases urinary hydroxytyrosol-glucuronide (HT-glucuronide) excretion in healthy young adults compared with regular olive oil (β = 1.24, 95% CI: 0.13–2.35, p = 0.028), confirming the absorption and metabolism of olive oil phenolic compounds.

Why this might work

When you eat extra virgin olive oil, it contains healthy chemicals called polyphenols. These polyphenols are absorbed from your gut into your body. Inside your body, they are changed into a different form called hydroxytyrosol-glucuronide. This changed form then leaves your body in your urine. Eating more polyphenol-rich olive oil means more of these chemicals get absorbed and changed, so more of the changed form ends up in your urine.

What the research says

1 study

  1. Study: Resting-state brain connectivity following extra virgin olive oil intake in healthy adults: a randomised crossover pilot neuroimaging substudy.

    The study found that people who drank extra virgin olive oil had more of a specific breakdown product in their urine compared to those who drank regular olive oil, which means their bodies absorbed the healthy chemicals.
